Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurence is located to the west of the Dome Stock and is primarily underlain by mafic volcanic rocks. Thick, massive diorite dikes intrude into the metavolcanic rocks. The basalt units are highly carbonatized and are generally quite massive. In places the mafic volcanics are strongly foliated along a NW-SE trend, and the foliation dips vertically. The mafic volcanics contain up to 20% quartz and carbonate stringers, and barren, white quartz veins up to 50 cm thick. Chalcopyrite is present along the foliation planes, along with minor pyrite and pyrrhotite. Ultramafic dikes (serpentinite) are intruded into the basalt units. DEPOSIT DESCRIPTION: Gold occurs in quartz and carbonate stringers, and in quartz veins in strongly foliated, highly altered basalt. The basalt unit is up to 20 m thick, but only thin zones have returned anomalous gold values. The quartz and carbonate stringers are quite small, and are mineralized with pyrite, pyrrhotite and chalcopyrite.
